After playing my two favorite rolls in CBT, I believe my "Main" will be a Blademaster named RaZoRBLaDeZ and my alt will be a Vanguard named Guardian. I found the Blademaster easier to level due to kill speed and Vanguards are best as a meat shield. Although I also like to heal, I am not as good as those who play this role on a regular basis.
CBT3 should be coming to an end soon & I hope to see you guys in game.
